We are told that f(x) = 2 - 4x and we want to find f(-5).

To do this, we put -5 in for x in all places on both sides of the equals sign. The left side tells us the input while the right side tells us the output.

f(x) = 2 - 4x

f(-5) = 2 - 4(-5)      <--------- notice how x and - 5 match

f(-5) = 2 - (-20)      by applying the multiplication of 4 and -5

f(-5) = 2 + 20        by applying the parentheses

f(-5) = 22


Thus, f(-5) is 22 and choice D is best.

In the image shown, line n is a transversal cutting parallel lines l and m. ∠2 = 2x + 50 ∠8 = x + 76 What is the measure of ∠2?
givi [52]

Answer:

Alternate exterior angles are congruent. So, set the angles equal to each other and solve for x.

2x + 50 = x + 76

x = 26

So, ∠2 = 2x + 50 = 2(26) + 50 = 102°

Luis, Diego, and Cecil are going fishing.
DIA [1.3K]

Answer:

7 worms

Step-by-step explanation:

Let each can have x worms, so we can say

Luis has 4x worms

Diego has 3x + 2 worms

Cecil has 2x worms

Since, in total they have 65 worms, we can write and equation and solve:

4x + 3x + 2 + 2x = 65

9x + 2 = 65

9x = 63

x = 63/9

x = 7

There are 7 worms in each can.

Answer:

<h2>Yes. It's a right triangle.</h2>

Step-by-step explanation:

If a ≤ b < c are the length of the sides of a right triangle, then

a² + b² = c².

We have:

a =30 ft, b = 40 ft and c = 50 ft.

Check the equality:

L = 30² + 40² = 900 + 1600 = 2500

R = 50² = 2500

L = R
